OILER.

Specification of Letters Patent.

Iatented May 29, 1906.

Application filed August 19,1905. Serial No. 274,913.

To a whom it may concern:

Be it known that I, DANIEL HERRMANN, a citizen of the United States, anda resident of Guttenburg, in the county of Hudson and State of NewJersey, have invented a new and Improved Oiler, of which the followingis a full, clear, and exact description.

My invention relates to oilers and admits of general use, but is ofpeculiar value in relation to oiling of wrist-pins, high and low speedengines, and other prime movers.

My invention is based upon the principle that a falling liquid is unableto follow a line of continually-changing direction at high speed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure 1 is a vertical section through a part of an engine equipped withmy invention. Fig. 2 is a vertical section of the same, taken at a rightangle to the view shown in Fig. 1.

The engine-cylinder is shown at 3 and is encircled by a water-jacket 4,and a piston is shown at 5. Connected with the cylinder and thewater-jacket is a supporting-frame 6. Bearings are shown at 7 and acurved web integral with the frame at 8. A twopart shaft 9 9 is mountedin the bearings 7 and is provided with a double crank 10, having awrist-pin 11. The connecting-rod is shown at 12 and is driven by thepiston 5. Mounted upon the connecting-rod 12 is an oil-plate 13,provided with a cupped edge 14 and secured to the connecting-rod bymeans of screws 15. Leadin downwardly from the lowermost portion of t ecupped edge 14 is an oil-duct 16 for supplying oil to the wrist-pin 11.An oil-cup is shown at 17 and is provided with a spout 18, extendingobliquely downward therefrom and passing through an aperture 19 in theframe 6, as will be understood from Fig. 1. The lower end of theconnecting-rod 12 is provided with a bearing 20, which encircles thewrist-pin 1 1.

The operation of my device is as follows: Motion being communicated fromthe piston 5 through the connecting-rod 12 to the wristpin 11 the latterrotates in a circle, and the oil-plate 13 rotates substantially in theform of an ellipse. The contour of the cupped edge 14 is likewisesubstantially that of an ellipse. Some part of the cupped edge 14 isalways maintained at a substantially constant distance from the lowerend of the spout 18. Oil being fed from the cup 17 through the spout 18drops constantly into the oil-plate 13 and finds its way downwardthrough the duct 16 to the wrist-pin 11,-

which is thus lubricated. No matter in what position the oil-plate 13may be when a drop of oil issues from the lower end of the spout 18 thedrop in question cannot be far from the cupped edge 14 and is broughtinto immediate contact with this edge by the motion of the oil-plate 13.If, for instance, the oilplate is descending in a curve and a drop ofoil is released adjacent to the cupped edge 14 at a point intermediatethe top and the bottom of the latter, the adjacent portion of the cuppededge 14 necessarily moves directly against the drop-that is, assumingthat the engine has a high speed.

The principle of the invention can readily be understood by assumingthat the speed of the oil-plate is higher than the speed with which thedrops tend to fall. Such being the case, each drop of oil when releasedfrom the shaft either falls into a portion of the cupped edge 14immediately adjacent to the end of the spout or else some other portionof the cupped edge 14 moves quickly from above or in a lateral directionagainst the drop, so that in any event the drop immediately makescontact with the inner or concave surface of the cupped edge. The oilnaturally gravitates downward to the oil-duct 16. I

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In an oiler, the combination of a connecting-rod,an oil-plate of substantially elliptical form mounted thereupon andprovided with a concave edge to guide the flow of oil, saidbearing-plate being further provided with a duct, a stationary oil-spoutprojecting to a point immediately adjacent to said edge for dischargingoil thereinto, and a bearing in communication with said duct and oiledthereby.

2. In a device of the character described, the combination of a crankprovided with a crank-pin, a connecting-rod provided with a bearingengaging said crank-pin, said connecting-rod being adapted to undergo ahigh speed, an oil-plate of substantially elliptical form connectedrigidly with said connectingrod and movable therewith in an orbitrepresented substantially by an ellipse, said oilplate being providedwith a cupped edge and with a duct leading from said cupped edge to saidbearing, and mechanism for discharging oil into said oil-plateimmediately adjacent to said cupped edge.

3. In an oiler, the combination of a connecting-rod, an oilplate mountedthereu on and adapted to move in a substantially e liptical orbit, saidoil-plate being provided with. a cupped edge of substantially ellipticalform, and a stationary spout so disposed relatively to said cupped edgeas to be always immediately adjacent to some portion thereof.

4. In an oiler, the combination of a bearing, an oil-plate communicatingtherewith and provided with a cupped edge having a substantiallyelliptical form, a stationary spout, and means for constantlymaintaining some portion of said cupped edge at a predetermined distancefrom said spout.

5. In an oiler, the combination of a connecting-rod having an angularmovement, an. oil-plate mounted upon said connecting-rod. and providedwith a cupped edge, a bearing connected with said oil-plate, and astationary spout projecting to a point immediately adjacent to saidcupped edge.

6. In an oiler, the combination of a bearing encircling a crank-pin, aconnecting-rod engaging said bearing and having an angular movement, amember mounted directly upon said connecting-rod and provided with acupped edge and with a duct leading from said cupped edge to saidcrank-pin, and an oil-spout projecting to a point adjacent to saidcupped edge for the purpose of feeding oil thereinto.

7 In an oiler, the combination of a connecting-rod adapted to moveangularly, an oil-plate mounted upon said connecting-rod and providedwith a surface adapted to guide the flow of oil and also provided with aduct, a bearing fed by said. duct, means for conferring upon saidconnecting-rod a comparatively high speed, and mechanism for dischargingoil immediately adjacent to said surface for guiding the flow of saidoil.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
